Do you buy or sell books at your local used bookstore? If so, you might not know it, but the clerks might secretly hate you.

That's not to say employees at these establishments are grouchy or miserable, it's just that there are a lot of things people don't understand about used bookstore procedures and etiquette. It's apparently such a common annoyance that both the Phoenix New Times and the SF Weekly have published articles about why your used bookstore clerk might just hate you.

A few of my personal favorites from the articles include people who rip the covers off of their books and don't understand why the store won't buy it, people who try to sell used phonebooks to the stores, and people who fall asleep in the crowded aisles.

Of course, I'm sure none of you intelligent, responsible Flossers partake in this kind of behavior, right?
